*Short answer is there's no problem.

Those numbers are a best-case scenario. I'm not sure what it takes to get there but most people don't max out the IOPS values. It's likely a number that could be achieved with a better SATA controller but I'm not sure.

I have exactly the same CPU and Motherboard, am using the best SATA controller from Intel on this board and get slightly lower numbers, but that's likely because you have the Rapid Cache feature enabled (which in reality doesn't usually benefit much so the score is a bit misleading).

My scores are:
548, 524
73989, 65624

My 840 PRO numbers are almost the same.

*In the real-world it's actually hard to tell the difference between an SSD that is 250MB/second and one that is 500MB/second.
